CORONAVIRUS UPDATE

Precision Digital Corp is open for business today and we are providing application and technical support and order entry as normal. However, due to interruptions in international supply chains, our ability to ship product has been severely hampered and we don’t expect that to change until late April.

Overview

Precision Digital offers three different light configurations in its line of Light / Horn devices. The first option is a factory ordered Light / Horn with a color of either red, green, yellow, blue, or white. The second option is a Light / Horn the user determines the light color (red, green, yellow, blue or white) by connecting the appropriate wire. The third option is a Light / Horn with red, yellow, and green layers the user can turn on independently. The light on the Light / Horn can be wired to flash (not available on PDA-LH5C) or stay steady on and the horn is rated at 85 dB. The light and horn can be controlled independently of each other via separate relays on the Precision Digital meter; and since the meter's relays can be reset in a variety of ways, there are several ways the Light / Horn can operate. For instance, the horn can be programmed to silence at any time via the Reset Button or F3 front panel button (on ProVu models), and light to turn off automatically when the alarm clears.

PDA-LH Series

ProVu and Helios Applications

There are a wide variety of ways these Light / Horn devices can be controlled by the ProVu’s or Helios's two or four relays to satisfy visual and audible alarm applications. Up to 8 relays are available on ProVu meters for even more versatility. Please feel free to contact tech support to discuss your particular application. The following examples illustrate some typical applications.

PDA-LH Models

PDA-LH Wiring

The PDA-LH models are the simplest devices in the Series and are made up of a single-color light and horn. A typical way to use the PDA-LH is to program the ProVu so the horn can be silenced at any time via the Reset Button or F3 front panel button, and light to reset automatically when the alarm clears:

4User DeviceAs user desires

PDA-LH5C

PDA-LH5C Wiring

The PDA-LH5C shows one color at a time and the light color (red, green, yellow, blue or white) is determined by which wires are connected to power through the meter’s relays. A typical application for the PDA-LH5C might involve lighting up the red light to indicate high and low alarms and the green light to indicate everything is OK using the meter's four internal relays:

2All OKGreen lightAuto
2High alarmRed lightAuto
3Low alarmHornLatch
4High alarmHornLatch

PDA-LH3LC-RYG

PDA-LH3LC-RYG Wiring

The PDA-LH3LC-RYG can light up red, yellow or green bands as determined by which wires are connected to power through the meter's relays. A typical application for the PDA-LH3LC-RYG (and the default factory setting) might involve lighting up the green light to indicate everything is OK, the yellow light to indicate a High warning, and the red light to indicate a High alarm. The Horn will also sound at both the Warning and High alarms and can be manually reset at any time with the front panel reset button:

3WarningHornLatch
4High alarmHornLatch

Control Stations for Remote Operation of Light/Horn

The PDA2360 series of plastic control stations provide a convenient way to remotely control the Light / Horn. The control stations can mimic the button on the front of the Helios for remote control of the Light / Horn. The PDA2361-R is used to reset an alarm, the PDA2361-A is used to acknowledge an alarm, and the PDA2361-Q is used to silence an alarm.

Control Stations
  • Complete Pre-Assembled Stations
  • Normally Open (NO) Spring Return Plastic Bezel Pushbuttons
  • IP65 / NEMA 4, 4X and 13 Rated
  • Control Station for Remote Operation of Light / Horn Reset Button
  • Wall Mountable

Connections

PDA-LH Connections

PDA-LH Models

Connections shown for a red light model. For other PDA-LH models, the red wire is the color of the light. Connect the red and black wires for a Steady On light and red and gray wires for Flashing light.

PDA-LH5 Connections

PDA-LH5C

Connect the LED color to the plus supply and the black wire to the minus supply to turn the LED on. Be aware of limitations for applications requiring different color lights for different alarm conditions.

PDA-LH3LC-RYG Connections

PDA-LH3LC-RYG

Connect the LED color to the plus supply for a Steady On light and LED color and gray wires to the plus supply for Flashing light. The black wire should be connected to the minus supply.

Transmitter Power Supply*: The ProVu's, Helios's, and Trident X2's internal transmitter power supply is capable of supplying 200 mA to power the transmitter and other devices such as the Light / Horn. The following table illustrates how much of this power is required to drive various Light / Horns. If more power is needed, then consider the PDA1024-01.
PDA-LH and PDA-LH5C Models:
Example: 17 mA (Red Light) + 20 mA (Horn) = 37 mA total current downgrade from the 200 mA supply. Left over current = 163 mA

ColorDowngraded by
Red17 mA
Green15 mA
Yellow23 mA
Blue15 mA
White42 mA
Horn20 mA

PDA-LH3LC-RYG:
Downgraded by each color that is turned on and the horn.
Example: 33 mA (Yellow Light) + 38 mA (Horn) = 71 mA total current downgrade from the 200 mA supply. Left over current = 139 mA
